Filed March 23, 195o Patented Mar. 11, 1952 UNITED STATES PATENT OFFICE ing in a building designed to receive the same and which frame carries aplurality ofA sash elements mounted therein for vertical slidable movement and so constructed and disposed within the frame as to be capable of removal or replacement therein from one side and to be intertted in engagement with each other and with parts of the frame structure to provide a weather-tight joint throughout.

Another object is to provide a combined window frame and sash construction wherein the sash guides provided on the frame are rformed by strips of sheet metalA suitably secured to the frame to constitute vertical guideways for dthe slidable sash andI which are so constructed that the sash may be individually removed from the guide channels upon the inside of the building, but the sash are held at all times securely against removal outwardly and' against accidentalV dis# placement and aweatherproof joint is formed between the sash and the frame and between cooperating sash elements. More particularly, theWindowV guide channels formed by the guide strips exhibit a continuous outer guide channelwall which extends from top to bottom of the frame while the inner wall of the' channel guide is divided into upper and lower portions separated substantially midway of the height of the window providing a gap at such point through which sash elements may be moved for insertion into the guide channel or withdrawal therefrom.

A meritorious feature is that the construction embodies a guide channel which exhibits throughout its upper portion a widthk suilcient only to receive a single sash element, while it exhibits throughout its lower portion awidth sufcient to receive two sash elements side by side. The combined window frame and sash structure shown herein includes three sash ele'- ments slidably mounted within the frame. Two of the sash elements shown are window' sash and the third sash element is a screen sash. It is possible with the construction illustrated to dis' pose the two window sash in superimposed relationship withone serving as a lowersashv and the otherpserving as an upper sash 'and with the screen storedy either inan elevated position or allowed to remain alongside of theI lower window sash. It is also possible to change this combination by elevating the lower window sash to an elevated stored position and placing the screen underneath the upper sash for ventilation u A meritorious feature exhibited in the sash elements is that the upper and lower sash rails are grooved lengthwise of the rails so that the upper and lower lsash will interfit with each other when one is? disposed above the other and the upper sash element will slightly overhang the lower one so as to form a weather-resistant joint. The grooving or these sash elements also cooperates with thelconstruction of the window frame assembly itself incertain positions. A sash element disposed in the lower position is mounted with the groove of its bottom rail nested over a ledge extending lengthwise of the sill of the frame assembly while its upper rail is interfltted with the bottom rail of a superimposed sash. The upper ends of the lower portions of the innerl guide" walls are adapted to serve as supports to bereceived within the groove of the lower rail of a-sasli disposed in the elevated stored position to maintain saidsash in such position.

The-window frame assembly exhibits a header portion which isv in the form of a downwardly openchannel that is relatively deep so that the top rail ofa sashelement may remain within the channel though the sash element is adjusted vertically within limits. y Inl addition, this header channel is of sufficient depth that a sash element may beraised thereinto-to a position of complete disengagement with another sash element disposed therebelow.

In the drawings the window frame and sash assembly is shown as mounted within a window opening wherein certain parts of the building adjacent the opening are illustrated in dotted outline, as follows: A sill portion is indicated as 26, a header portion as 22, and opposed complementary jamb portions as 24. In a copending application of the same inventor, illed of the same date herewith, Serial No. 151,377, the particular construction of the frame and specifically the manner in which it is adaptable to t window openings of slightly dilferent size or slightly out of plumb relationship is illustrated and claimed. This case relates to the combination of the frame and sash structure.

The frame itself is formed of sheet metal parts, as more particularly described in the copending application above referred to. There are complementary opposed jamb portions 26 which in cross section are in the form of outwardly open channels each exhibiting an inner folded side wall 28 that rests against the jamb face of a jamb part of the building. Each channel also exhibits an outer side wall folded upon itself and indicated by the numeral 30. This outer side wall is of greater width than the inner side wall and, as shown particularly in Figs. 3 and 4, overlaps the building wall adjacent the window opening.

The outer side wall of each jamb channel is sorfabricated as to exhibit an inwardly projecting flange portion 32 which is continuous therewith and with the bottom of the channel and is disposed in approximately the same plane as the outer wall 30 and constitutes an outer guide wall of a sash guide channel, as shown particularly in Figs. 3, 4, and 6. This outer guide wall 32 extends for substantially the height of the window frame. Each jamb portion is provided with an inner guide wall and this inner guide wall is divided into upper and lower portions. The lower portion of each inner guide wall is shown in the form of a flat metal strip 36 held between the folded over margin 28 of the inner side wall of the jamb channel, as shown particularly in Figs. 4 and 6. As illustrated in Fig. 4 and as particularly set forth in the copending application supra, this strip may be held in place by indentations 4D in the thin sheet metal.

The upper portion of each inner guide wall is. in the form of a strip of sheet metal fashioned into angular shape, as shown particularly in Figs. 3 and 5. Each such angular strip has one marginal portion 42 which is received between the lower part of the folded over ilange 28 of the inner side wall of the jamb channel and held therein by indentations 40, as heretofore described. This angular upper inner guide wall has another portion 44 which rests directly upon the jamb face of the window jamb element and has a marginal portion 46 that is disposed substantially normal to the portion 44 and constitutes the guide wall proper for the sash channel guide and cooperates with the outerv guide wall 32 to establish this guideway for the sliding sash..v

These jamb portions of the window frame have their upper ends seated within and secured within a downwardly open header channel 50, as shown :particularly in Figs. '7, 8 and 9 and also Figs. l and 2. This header channel has its inner wall of greater width than its outer wall and the lower margin is Vbent as at 52. To mount this structure against the header of a window opening, a channel part 54 is secured by nails or the like to the header of a window opening and is capable of receiving the header 50 of the window frame assembly and retaining the same snugly therein, as shown particularly in Figures 7, 8

and 9.

The sill portion of the window frame assembly is illustrated particularly in Fig. 6 and includes an upwardly open sheet metal channel 58. The lower ends of the jamb portions are seated within this channel and secured to the side walls within a window opening there is provided a sill plate 62 which is slidably received between the overlapping outer side walls of the two sill channels 58 and 60, as illustrated particularly in Figs. 6, '7 and 8. The ends of this plate 62 are folded as at 66 over the outer margin of the outer side wall 38 of the jamb channel, as illustrated in Figs. 2 and 6. This jamb plate is adjustable vertically. In Fig. 6 the dotted line shows a lowered position. It is adjustable so that its outwardly flanged margin 66 may rest upon a sloping face of a sill part of a window opening.

The said assembly also includes a weatherstrip part which is seated over and held in place upon an upwardly projecting flange stop 68 of the sill channel part 68. This upwardly projecting ilange 68 is formed integrally with the sill 60 and lies approximately within the plane of the inner side wall of this sill channel 60. It constitutes an inner stop for a sash element when lowered. It also constitutes a seat for the sill weatherstrip element 16. This weatherstrip element 10 is seated over the stop part 68, as shown in Figs. 6, 7, 8 and 9. It grippingly engages the stop part 68 so as to maintain its position thereover. This weatherstrip 1U has a portion l2 that seats upon the sill face of the sill portion of the window frame. It also has a marginal portion I4 that is turned upwardly so as to constitute a seat for a sash element disposed in the lowered position, as shown in Figs. 6, '7 and 8.

This marginal portion 'I4 is disposed outwardly from the sash stop 68 a distance greater than the thickness of one of the sash mounted within the window frame. The sash mounted within the window frame are shown as of uniform thickness. The width of this spacing of the flange 'I4 from the sash stop 68 is, however, less than the thickness of two sash elements and less than the width of the sash guide channel at the bottom by approximately one half of the thickness of a sash element. In other words, as shown in Figs. 6 and 7, a screen sash identified as S and the bottom rail of a lower window sash identified as L are mounted side by side within the lower part of the sash guide channel and the screen sash is seated upon the upturned flange 14. This forms a weatherseal. The construction is such also that the screen sash is held against the outer wall 32 of the sash guide channel.

The upper and lower sash rails are provided with grooves 16. As shown in Figs. 6 and 7, the groove in the lower sash rail of the screen is seated over the ledge 'M of the weatherstrip'l. The groove inthe upper sash rail of this screen is intertted, as shown in Fig. 7," with the groove in the lower sash rail of the upper window. This constitutes a weather seal at both places and the window, of course, is sealed at the top because the top rail of the sash element is grippingly held between the outer guide wall 32 and theinner guide wall 4d of the sash guide'channel andbetween the outer side wall of the header` channel and the inner guide rail d4. In Fig. '7 the lower window sash is shown in a lowered position alongside of the screen within the lower part of the sash guide channel between the lower sash guide rail 38 and the outer guide rail 32 of the sash guide channel.

This lower sash may be raised to a stored elevated position, as shown in Fig. 8, by elevating the same from the position shown in Fig. 7 to that shown in Fig. 8 and seating the groove of the lower rail of the window over the upper ends of the inner guide walls 32. The upper rail of the elevated window is irictionally gripped in position in the header and the window is securely held in such elevated position. The lower rail of this window sash is provided with a latch or handle part 'E6 whereby it may be more conveniently manipulated. When it is desiredv to remove the screen or to replace it with another sash, or torernove all the sash from the window frame, the lower window may be removed directly from the position shown in Fig. '7 or it may be elevated from the position shown in Fig. 8 to disengage its lower rail from the upper ends of the inner lower guide walls and then lowered inwardly of the assembly and removed therefrom, being moved through the gaps between the upper and lower sections of the inner guide rail of the sash guide channels. To facilitate the insertion of the upper end of the elevated stored sash into the header opening, the lower margin of the inner wall of the header channel is bent, as shown at 52. The screen may be removed from the position shown in Figs. 7 and 8 by elevating the upper window sash so as to disengage it from the screen and then withdrawing the screen upwardly and inwardly through the gap between the upper and lower portions of the inner walls of the sash guide channel, all as shown in Fig. 9.

The sash elements may be replaced within the assembly frame in the window frame through the gap between the upper and lower portions of the inner walls of the sash guide channels.
